Introduction:
   Currently we mainly provide corrugated expansion joint with stainless steel bellows. It is well designed and easy to install, suitable for all-around compensation. It is resistant to pressure, corrosion, fatigue, heat and cold impact. It can be used in piping engineering in varied fields, like petrochemical, steel, machinery, ship building, construction, pharmaceutical etc.

Specifications:

    → Single angular ( DJ ) corrugated expansion joint
    Nominal pressure : 0.1-1.6Mpa
    Working temperature : -20 - 400oC
    Fatigue life : 3000'
    Description :
    1. Single bellows. It will deflect in the plane axial to the pin roll, and does not cause internal pressure.
    2. It can be used in a double or triple set for axial compensation, or in combination with lateral compensators for L or Z type thermal expansion.

    → Single normal ( DT ) corrugated expansion joint
    Nominal pressure : 0.1-2.5Mpa
    Working temperature : -20 - 400oC
    Fatigue life : 3000'
    Description :
    1. Single bellows. Mainly used for axial thermal expansion compensation or shock/noise absorbing.
    2. Flanges according to JB81-59. ( Also for the following types of expansion joints. )
    3、Further technical data available upon request. ( Also for the following types of expansion joints. )

    → Single axial ( DZW ) expansion joint
    Nominal pressure : 0.6-1.6Mpa
    Working temperature : -20 - 400oC
    Fatigue life : 3000'
    Description :     
    1. Resistant to destabilization, with more convolution in bellows,3-4 times more effective than normal type.
    2. Outer cover available for protection of bellows.

    → Single all-around ( DW ) expansion joint
    Nominal pressure : 0.1-1.6Mpa
    Working temperature : -20 - 400oC
    Fatigue life : 3000'
    Description :     
    1. It will deflect in any direction or plane that the bellows will, and cause no internal pressure.
    2. It can be used in a double or triple set for axial compensation, or in combination with lateral compensators for thermal expansion control of complicated pipe system.

    → Multi lateral ( FH ) expansion joint
    Nominal pressure : 0.1-2.5Mpa
    Working temperature : -20 - 400oC
    Fatigue life : 3000'
    Description :     
    1. It can compensate lateral deflections in any direction, and will not cause internal pressure.
    2. It is suitable for compensation of L or Z type pipe deflection.
